The Pfitzner Performance Gearboxes (PPG) HL-T56H4G-GM-GA is a high-performance H-C dog set for T56 6-speed manual transmissions, specifically engineered for GM applications. The set includes specific gear ratios to optimize performance: 1st gear at 2.946, 2nd gear at 2.071, 3rd gear at 1.438, and 4th gear at 1.000. The fifth and sixth gears maintain standard ratios.
